Logic of controlling compressor and fan of condensing units ASE-xxAH
1, For 18,24,36K units,
All the outdoor fan have a outdoor fan with fixed speed. Normally the outdoor fan runs with the compressor. The outdoor fan starts when the
compressor starts, and stops when the compressor stops. And their running status are determined by the difference between indoor and setting
temprature.
The control logic:
When in cooling mode,

2, For 48K and 60K units,
Some are with single fan and some are with twin fans,
For the units with single fan, the fan motors have two speeds; :
when in cooling mode,
When in heating mode,
For the units with two outdoor fan motors, in some occasions, one motor will stop:

b. The stop value of the outdoor unit should be closed absolutely (as original state). Every time you
connect it, first loosen the nuts at the part of stop value, then connect the flare pipe immediately (in 5
minutes). If the nuts have been loosened for a long time, dusts and other impurities may enter the pipe
system and may cause malfunction later. So please expel the air out of the pipe with refrigerant before
connection.
c.
2)
a.
b.
Expel the air after connecting the refrigerant pipe with the indoor unit and the outdoor unit. Then fasten
the nuts at the repair-points.
Locate The Pipe
Drill a hole in the wall (suitable just for the size of the wall conduit), then set on the fittings such as the
wall conduit and its cover.
Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which will
cause water leakage by condensation.
c.
Pass the bound connecting pipe through the wall conduit from outside. Be careful of the pipe allocation
to do no damage to the tubing.
3)
Connect the pipes.
4)
Then, open the stem of stop values of the outdoor unit to make the refrigerant pipe connecting the
indoor unit with the outdoor unit in fluent flow.
5)
Be sure of no leakage by checking it with leak detector or soap water.
6)
Cover the joint of the connecting pipe to the indoor unit with the soundproof / insulating sheath (fittings),
and bind it well with the tapes to prevent leakage.
2. Vacuum Dry and Leakage Checking
2.1 Vacuum Dry: use vacuum pump to change the moisture (liquid) into steam (gas) in the pipe and
discharge it out of the pipe to make the pipe dry. Under one atmospheric pressure, the boiling point of
water(steam temperature) is 100℃. Use vacuum pump to make the pressure in the pipe near vacuum
state, the boiling point of water falls relatively. When it falls under outdoor temperature, the moisture in
the pipe will be vaporized.
2.2 Vacuum dry procedure
There are two methods of vacuum dry due to different construction environment: common vacuum dry,
special vacuum dry.
①. Common vacuum dry procedure
l Vacuum dry (for the first time)---connect the all-purpose detector to the inlet of liquid pipe and gas pipe,
and run the vacuum pump more than two hours (the vacuum pump should be below -755mmHg)
l If the pump can’t achieve below -755mmHg after pumping 2 hours, moisture or leakage point will still
exist in the pipe. At this time, it should be pumped 1 hour more.
l If the pump can’t achieve -755mmHg after pumping 3 hours, please check if there are some leakage
points.
l Vacuum placement test: place 1 hour when it achieves -755mmHg, pass if the vacuum watch shows no
rising. If it rises, it shows there’s moisture or leakage point.
l Vacuuming from liquid pipe and gas pipe at the same time.
l Sketch map of common vacuum dry procedure.
②. Special vacuum dry procedure
l This vacuum dry method is used in the following conditions:
l There’s moisture when flushing the refrigerant pipe.
l Rainwater may enter into the pipe.
l Vacuum dry for the first time ······ 2h pumping
③. Vacuum destroy for the second time ······ Fill nitrogen to 0.5Kgf/cm 2
Because nitrogen is for drying gas, it has vacuum drying effect during vacuum destroy. But if the moisture is
too much, this method can’t dry thoroughly. So, please pay more attention to prevent water entering and
forming condensation water.
④. Vacuum
dry for the second time······1h pumping
Determinant: Pass if achieving below -755mmHg. If -755mmHg can’t be achieved in 2h, repeat procedure ③
and ④.
⑤.
Vacuum placing test ······ 1h
⑥. Sketch map of special vacuum dry procedure
3. Additional Refrigerant Charge
Caution
● Refrigerant cannot be charged until field wiring has been completed.
● Refrigerant may only be charged after performing the leak test and the vacuum pumping.
● When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in
view of the danger of liquid hammer.
● Charging with an unsuitable substance may cause explosions and accidents, so always ensure that the
appropriate refrigerant is charged.
● Refrigerant containers shall be opened slowly.
● Always use protective gloves and protect your eyes when charging refrigerant.

4. Water Drainage
4.1 Gradient and Supporting
4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as
possible and eliminate the air bubble.
4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to
keep the gradient of 1/100 and prevent bending. Refer to the following table for the specification of the prop
stand.
Hard PVC pipe
Diameter
Distance between the prop stands
25~40mm
1.5~2m
4.1.3. Precautions
① The diameter of drainpipe should meet the drainage requirement at least.
② The drainpipe should be heat-insulated to prevent atomization.
③ Drainpipe should be installed before installing indoor unit. After powering on, there is some water in
water-receiver plate. Please check if the drain pump can operate correctly.
④ All connection should be firm.
⑤ Wipe color on PVC pipe to note connection.
⑥ Climbing, horizontal and bending conditions are prohibited.
⑦ The dimension of drainpipe can’t less than the connecting dimension of indoor drainpipe.
⑧ Heat-insulation should be done well to prevent condensation.
⑨ Indoor units with different drainage type can’t share one convergent drainpipe.
4.2 Drainpipe Trap
4.2.1. If the pressure at the connection of the drainpipe is negative, it needs to design drainpipe trap.
4.2.2. Every indoor unit needs one drainpipe trap.
4.2.3. A plug should be designed to do cleaning.
4.3 Upwards drainage (drain pump)

4.4 Convergent drainage
4.4.1. The number of indoor units should be as small as possible to prevent the traverse main pipe overlong.
4.4.2. Indoor unit with drain pump and indoor unit without drain pump should be in different drainage system.
4.4.3. Selecting the diameter
Number of connecting indoor units→Calculate drainage volume→Select the diameter
Calculate allowed volume =Total cooling capacity of indoor units(HP)×2 (l/ hr)

4.5 Drainage test
4.5.1Drainage without drain pump
After finishing drainpipe installation, pour some water into the water receiver plate to check if the water flows
smoothly.
4.5.2 Drainage with drain pump
① Poke the Water Level Switch, remove the cover, use water pipe to pour 2000ml water into the water
receipt plate through the water inlet.
② Turn on the power to Cooling operation. Check the pump’s operation and switch on the Water Level
Switch. Check the pump’s sound and look into the transparent hard pipe in the outlet at the same time to
check if the water can discharge normally.
③ Stop the air conditioner running, turn off the power, and put back the cover.
Stop the air conditioner. After 3 minutes, check if it has abnormity. If the collocation of drainpipes is
illogical, the water will flow back overfull, which will cause the alarm lamp flashes, even overflow from
the water receipt plate.
l Keep on pouring water until it gives an alarm signal for high water level, check if the pump drains water
at once. If the water level can’t fall below the alarmed water level after 3 minutes, the air conditioner will
stop. Turn off the power and drain the remained water, and then turn on the air conditioner.
Note: the drain stuff in the main water receipt plate is for maintenance. Stuff up the drain stuff to prevent water
leakage.

5. Insulation Work
5.1 Insulation material and thickness
5.1.1. Insulation material
Insulation material should adopt the material which is able to endure the pipe’s temperature: no less than
70℃ in the high-pressure side, no less than 120℃ in the low-pressure side(For the cooling type machine, no
requirements at the low-pressure side.)
u
Example: Heat pump type----Heat-resistant Polyethylene foam (withstand above 120℃)
Cooling only type----Polyethylene foam (withstand above 100℃)
5.1.2. Thickness choice for insulation material
Insulation material thickness is as follows:
Refrigerant pipe
Drainage pipe
Pipe diameter (mm)
Φ6.4—Φ25.4
Φ28.6—Φ38.1
Inner diameterΦ20—Φ32
Adiabatic material thickness
10mm
15mm
6mm
5.2 Refrigerant pipe insulation
5.2.1. Work Procedure
① Before laying the pipes, the non-jointing parts and non-connection parts should be heat insulated.
② When the gas proof test is eligible, the jointing area, expanding area and the flange area should be heat
insulated
5.2.2. Insulation for non-jointing parts and non-connection parts
wrong
Gas pipe and liquid pipe should
not be put together to insulate
right
Insulate the gas pipe
(cooling only)
Insulate the gas pipe and
liquid pipe
For construction convenience, before laying pipes, use insulation material to insulate the pipes to be deal
with, at the same time, at two ends of the pipe, remain some length not to be insulated, in order to be welded
and check the leakage after laying the pipes.
5.2.3. Insulate for the jointing area, expanding area and the flange area
① Insulate for the jointing area, expanding area and the flange area should be done after checking leakage
of the pipes
② Make sure there’s no clearance in the joining part of the accessorial insulation material and local
preparative insulation material.
5.3 Drainage pipe insulation
The connection part should be insulated, or else water will be condensing at the non-insulation part.
5.4 Note
5.4.1 The jointing area, expanding area and the flange area should be heat insulated after passing the
pressure test
5.4.2 The gas and liquid pipe should be heat insulated individually, the connecting part should be heat
insulated individually.
5.4.3 Use the attached heat-insulation material to insulate the pipe connections (pipes’ tie-in ,expand nut ) of
the indoor unit
6. Wiring
Please refer to the Wiring Diagram.
7. Test Operation
